Have you seen these defects?


Two years ago I bought a refurbished D810 directly from Nikon. I shoot mostly landscapes – low volume photography. Therefore my camera has less than 5,000 actuations…

About six months ago I started noticing two types of strange visual defects appearing in my images. I’m not sure if they are related:

Defect #1: dark streak, randomly appearing in the upper left side of the frame

Defect #2: dark pattern, identical shape located in the same area by the upper left frame line.

These defects repeat in about every 50 – 100 frames, regardless of what lens or shutter speed I use.

I’m attaching a few samples to demonstrate what I’m concerned about. None of these files were processed, only converted to JPG in View-NX-i to save space.

Please have a look and let me know what you think the problem could be.

Thank you,
